NOTE: The GPS 500 always navigates TO a waypoint unless the OBS switch is set (preventing
automatic waypoint sequencing), or you have passed the last waypoint in your flight plan.
Directly above the CDI appears the active leg of your flight plan, or the direct-to destination when using
the direct-to key. This automatically sequences to the next leg of your flight plan as you reach each interim
waypoint. If no flight plan or direct-to destination has been selected, this line remains blank.
The scale of the “look ahead” map display appears in the bottom left corner. Nine scale settings,
ranging from 5.0 nm to 200 nm are available. Use the RNG key to select the desired scale.
To adjust the map scale:
1. Press the up arrow on the RNG key to zoom out to a larger area. 
OR,
2. Press the down arrow on the RNG key to zoom in to a smaller area.
Selecting Desired On-Screen Data
At the corners of the Default NAV page, four user-definable fields display the data you need as your
flight progresses. By default, these fields display: desired track (DTK), distance to destination (DIS),
ground speed (GS) and estimated time en route (ETE). However, each of these fields can be custom-
tailored to your preferences by selecting a different data item. Fuel flow is selectable with valid sensor
data installed. Available data items include:
• Bearing to destination (BRG)
• Cross track error (XTK)
• Distance to destination (DIS)
• Course to steer (CTS)
• En-route safe altitude (ESA)
• Desired track (DTK)
• Estimated time en route (ETE)
• Estimated time of arrival (ETA)
• Total fuel flow (FLOW)
• Ground speed (GS)
• Minimum safe altitude (MSA)
• Track angle error (TKE)
• Ground track (TRK)
• Vertical speed required (VSR)
